Hello Chris,
Quickly tested grep (egrep) here and, yes, options -i and -o don't gracefully co-exist. Thanks for having taken the time to report that one.
Of course, against precise cases, one could code for case-insensitivity, as in:
[...] /usr/bin/grep --only-matching '<[aA] [hH][rR][eE][fF][^>]+\\.[jJ][pP][gG][^>]*>'"
but this doesn't make the bug disappear...
Have you submitted a bug report?
Axel
